Improved water-wheel



UNITED STATES PATENT OFFICE.

JESSE BARTOO, OF EAST AURORA, NEV YORK.

IMPROVED WATER-WHEEL.

Specification forming part of Letters Patent No. 20,157, dated May 11, 1858.

Be it known that I, JESSE BARTOO, of East Aurora, in the county of Erie and State of New York, have invented certain new and useful Improvements Relating to the Arrangement and Operation of VaterJVheels; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification.

The nature of my invention consists in the employment of a cast-iron segment, an adj'asti able band, and semi-cylindrical cap in combination with a water-wheel for the purpose of adjnstability and the protection of the wheel against unequal wear and waste of water.

To enable others skilled inthe art to make and use my invention, I will proceed to describe its construction and operation.

Figure l is a perspective view of the penstock with the wheel suspended and arranged therein. Fig. 2 is a perspective of the adjustable band. Fig. 3 is a perspective of the cast-iron segment. Fig. 4- is a perspective of the semi-cylindrical cap. Fig. 5 is a side elevation of the pen stock with the cast-iron segment connected therewith. Fig. 6 is an end elevation of the penstock and bot-h segments, the wheel and semi-cylindrical cap being removed.

Letters of like name and kind refer to like parts in each of the figures.

A, Fig. l, represents the frame-work of thel penstock.

B is a reaction-wheel. It has its duplicate on the other end of the shaft.

C is a semi-cylindrical cap. This is made of sheet metal and sets over the wheel-shaft between the two wheels. It connects with the cast-iron segn'lents and forms a circle therewith. It is movable at pleasure and, together with the bands D, is adjustable relatively to the wheel.

D is an adjustable iron band. This band clasps the iiange I of the cast-iion-seglne1it, and it also clasps the semicylindrical cap C, holding them securely together and preventing the waste of water. The bands are adjustable, and when in place are of the same diameter as the wheels. They are set so as to come lightly in contact with the rim of the wheels, allowing the wheels to rnn freely, and yet sufiiciently close to prevent much loss of water. If the wheels become obstructed by sticks or any foreign substance, these bands may be loosened and the obstruction easily removed. d2 shows a bolt which connects the projecting ends of the band.

E is the Wheelshaft.

F is a plumb-block for gudgeons of wheelshaft. It is fastened to the frame of the peustock at 7L 71. This has its duplicate on the other end.

II, Fig. S, is a cast-iron segment. This is fastened to the penstock by one of its flanges, the other Harige projecting to receive the band; 2', a Harige of the segment over which the band clasps; j, an inner tlange,"whiel1 is bolted to the timbers of the penstock K, a flood-gate, which may be opened and shut at pleasure.

A conca-ve metal plate is placed in rear of the wheel and connected with the penstock, and makes a part thereof, which forms a chute to conduct the water to the wheel.

The band D can at any time be easily loosened and the cap removed, and the wheel thereby made accessible, so as to remove any obstruction and put the same in order. 4The band may be moved in either direction and at all times made adjustable to the wheel, and

thereby compensate for any wear or friction of the wheel against the band, and also prevent any undue escape of the water. This arrangement is also applicable to a wheel revolving upon a vertical shaft.

I claim- The iron segment II, in combination with the adjustable band D and semifcylindrical cap C, for the purposes substantially as herein set forth.

JESSE BARTOO.
